SPECIFICATION, forming ea of Letters' Patent ivofeeigees, dated' January s, 1384. F

l Application filedlfay11,1883. (No modal I To alt whom it may concern.-

' Be it known that I, AUGUSTINE SAOKETT, a citizen of the United States, and resident .of New York, in the county and State of New 5 York, have invented certain new and useful Improvements in Rooting-Felt and Mechanism for llIaking the Same, of which the following is a specification, when taken in connection, with the accompanying drawings, forming a- Figure 1 is a vertical longitudinal sectional view of my machine. Fig. 2 is an end view; and Fig. 3,is a'plan view of the coated fabric,

- the dark lines showing the pitch or bituminous 1 I5 layer as applied by the roller.

In a former application, filed by me October 28, 1882, Serial No. 75,334, and allowed February 7, 1883, I have shown, described, and

' claimed a roofing' -felt made up of threelayers or webs of felt or paper, theinner layer or web being narrower than the two outer layers, said inner layer being saturated'or coated, orboth saturated and coated,with coal-tar and pitch, or natural bitumen, or other materials suitable 2 5 for the purpose, said inner layer or webbeing joined to the outer layers or webs, so that their edges will project over the edges of the inner layer or web and thus form a dry uncoated margin, which will prevent the'pitch or other cementing material from runningover the.

edges of the fabric, and causing the layers to adhere when wound upin a roll for transportation and-use.. I

In my former application I have described in the original specification the substance of I this invention, but have preferred not to claim it therein, reservingit, inconnection with the mechanism for making, to form the subjeotmatter of this application.

o My present invention,therefore, consistsin applying to a, web or'layer of roofing felt, pa-' per, or other material a coating of bitumen, either natural or artificial, in such a manner lthat the edges thereof will extend beyond the edges of the cement,leaving anarrowmargin on each side free from the cement, andthenjoining to the fabric thus coated another layer or web of felt, paper, or other material of equal width, so that the completed article-Will be i 5o composed of two sheets or webs. of felt or par per, united, except at its edges, with a layer of bituminous or other cement. My invention are m ounted-the de consists, further, in the mechanism for making my improved fabric. v f

I will now'proceed to describe my devices for maliin r the improved roofing felt; but other devices equally applicable may be used without departingfrom th e spirit-of my invention.

, A is the frainc of' the machine, which may be made of any suitable material, in which yices, to be more fully hereinafter described.

B isa tank or vat, in which the pitch, 820.,

is melted and heated, of anysuitable construction, and in which is located a coil of steampipes, v0, for Heating the pitch or rial used in coating the felt.

D isa roller or drum, so mounted as to be partially submerged in thepitch within the tank. The said web of .feltor paper being caused to impinge against the cement on the roller D in its passage through the machine other 'mate by means of the roller or .drum E, which is mounted in adjustable bearings, so that the space between tl'ienollers on drums D and E can'be regulated to admit of felts or paper of different thicknesses passingthrough, and at the sametime apply "a coating of the pitch -'or cement of the required thickness.

The roller-or drum D is made somewhatshorter than the width of the felt which is to be coated, so that when thepitch is appliedrthere will be amargin of half an inch, 'more or less, onwhich there will be no pitch, so that when the layer of felt orpaper which is unwound from the roll Fis caused to come in contact with the coated web or layer of felt a, there will bea margin or dryedge on each side of the web, which will prevent the pitch from working, out" over the edges of the-same, and prevent the-different layers or convolutioiis of felt from adhering together when it is wound ina rollready for use. The shaft of the roller or drhm D is provided with a band-wheel, G, by which means power is applied from. any suitable source to rotate the roller or'drum D; Thisdrnni D is rotated at a greater or less velocity than that at which the web a of felt or paper travels, which causes said roller to, apply a more perfect and even layer of cmentto the web a than would be the case if the web and drum traveled at the 'same'rate of speed. I prefer, however, to run ent confined inthe interior thereof,

' paper-or felt, and

I paper or felta the roller-drum D faster than the traveling claim, and desire to sec of the web-, for by this meansa good of cement is constantly applied to the at the same time, by the of the roller E, the roller,

to remove the surplus of I speed supply proper adjustment D act-s asa scraper estates material, and also-applies 'the coating of cement in'a' uniform layer to the felt 'or paper.-

roller E is mounted and brings the paper or As heretofore stated, the in adjustable bearings,

felt from off the roller H in contact with the cement at "a point where the two rolls E meet, thus insuring an even distribution of I .drum,

the cement.

I is a roller, over which the coated web of passes, and at which point it is.

D and joined by the web I), as it is unwound from the roller-F, the two webs or layers of .felt, orpa per being united and wound into, a roll gnthe roller J.

'The rollers l) and J are power vdriven rolls.

The former, D,is driven for the purpose'already described, while the-objectof applying power. to the latter, J, is to draw the felts through the machine, while the rollers E, -H, I, and F are -rotated by the passage of the web' over or from them.

- This machine can be readily adapted for,

making the threeply felt described in my application heretofore referred to by raising the roller E, so it and the felt a will'not come in contact with the roller D, and placing a web or roll of narrower felt on the roller K, and allowing it to become saturated orcoated on both sides by passing it beneath the roller D,

into the coating material, andthence between therollers Band I. asshown in dotted lines I in Fig.1. The

"departing from webs of felt a and b may be previously saturated with coal-tar, or mixtures of the same, .and dried before theyare joined together in the machine by'any of the wellknown devices or processes now in use;

but

this is not essential where the material is to be used as a sheathing 'erable,

5' .It' will be seen paper or felt, in which case unsaturated paper "or felt would be pref and they may be thus joined without the spirit of my invention.

from the description given that I make a felt for roofing and oth'erpurposes with a coating'or body of pitch or cem while the edges will be free from/the tarry and sticky compound and,furthermore,the body of cenrent is practicallysealed within the external layers of felt or paper,

the atmosphere and sun is prevented, thus rendering the fabric: more durable.

Having thus described my invention,

what

herein described of coating the same consisting in which is somewhat shorter than the widthfof thefelt, whereby a layer of pitch or cement is applied to the webon all portions ure by Letters Patent,

of felt or fabric in. contact with a partially-submergedroller or of. it, except in a nar'row marginal line or space i i v Q at'each edge.

same consisting inlbringing a traveling web offelt or paper in contact with a rapidly-revolve ingsaid drum through the machine, as set forth I 4.- The methodherein deseribedofunanufacturing roofing felt or paper 1 or other, material of like character, the same consisting in ap-' plying a layer of pitch or cementloalayer or the'short power-driven roller-.D, mounted so nation with the adjustable roller E, roller H, and-traveling web as set forth.
